Modeling in mirror?

Eventually yes, but I don't think it will be for V1.

However, there is a limited form you can do right now by using history. After you mirror an object, you can select the result and enable history updates on it (through Edit/History). Now when you adjust control points or move around the original object, the mirrored one will update through the history update mechanism.
